Menma is a very cheerful girl with a very air-headed nature. She's kind and often worries about others before herself, especially when it comes to Jintan. She is extremely childish, although this may partially be down to the fact she died as a child and has only recently been "resurrected".

Otaku Trivia:

1) She makes an appearance in episode 1 of the anime Saenai Heroine no Sodatekata as figurines.

2) Menma's nickname is derived from combining the beginning of her given name (めいこ) with the end of her surname (ほんま). The word menma (メンマ) also refers to a type of pickled bamboo shoots.

3) Although throughout the series she is surrounded by her friends, she does often get very lonely and upset easily, especially when she visits her family and realizes she no longer belongs to them, nor does she have a home.
